Optical FiberCommunication :

Introduction :

Introduction Fiber optics (optical fibers) are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances.

Parts of Optical Fiber :

Parts of Optical Fiber Core
Cladding
Buffer Coating

How Does an Optical Fiber Transmit Light? :

How Does an Optical Fiber Transmit Light?

Physics of Total Internal Reflection :

Physics of Total Internal Reflection The angle of the light is always greater than the critical angle
Cladding does not absorb any light from the core
The extent that the signal degrades depends upon the purity of the glass and the wavelength of the transmitted light
